Definitions

  • An embodiment of the present invention relates to a wiring film, a device transfer sheet, and a textile type device.
  • Patent Document 1 includes a strain-sensor-attached cloth including a strain sensor having a carbon nanotube film attached to a cloth and a wiring part connected to the strain sensor.
  • Patent Document 2 includes cloths in which a wiring part is integrally provided on a cloth main body.
  • the wiring part is integrated with the cloth main body so that it becomes difficult for the wiring part to be cut and it is possible to minimize interference with a wearer's motion with the device.
  • one end of the wirings is connected to an electrode of the sensor but the other portion thereof is not fixed to a base member or the like. For this reason, when the number of wires increases, the wiring itself interferes with the wearer's hand motion or interferes with the wearer's movement.
  • the wiring part is directly formed on the cloth main body. Since a thread-like body having conductivity is knitted into the cloth, it cannot be said that conformability with respect to deformation or tension is sufficient. Furthermore, a short circuit between wirings may occur due to contact between wires, with sweat, or the like in some cases. Since the cloth is easily deformed even if it is attempted to adhere insulating layers to both surfaces of the wiring part to prevent a short circuit, it is difficult to position the insulating layers. In addition, there is a concern that impairment of stretchability or air permeability occurs due to the adhered insulating layers.
  • the present invention was made in view of the above circumstances, and an object of the present invention is to provide a textile type device in which there is less discomfort at the time of wearing the device and capable of minimizing occurrence of short circuits or the like. Furthermore, an object of the present invention is to provide a wiring pattern which can be suitably used for a device transfer sheet and a device transfer sheet which can be easily attached to a cloth in which the textile type device is deformed.
  • the inventors of the present invention found that a device transfer sheet having high flexibility can be obtained by forming wirings in a film having excellent stretchability.
  • the inventors found that a textile type device in which there is less discomfort and which causes hardly any problems such as a short circuit at the time of wearing the device using the device transfer sheet can be obtained, thereby completing the present invention.
  • the present invention adopts the following means.
  • a wiring film according to an embodiment of the present invention can be used as a wiring film for a device transfer sheet because the wiring film has adhesive properties and high stretchability.
  • an electronic component in which wirings are provided can be easily transferred to a cloth and a short circuit does not occur in the wirings.
  • a textile type device causes less discomfort and hardly any problems such as a short circuit at the time of wearing the device.
  • Fig. 1 is a schematic plan view of a textile type device according to an embodiment of the present invention.
  • a textile type device 100 includes a cloth 50, a plurality of electronic components (sensors) 20 provided in the cloth 50, a circuit board 30 in which information from the sensors 20 is integrated, an external output means 40 for outputting the information integrated in the circuit board 30 to the outside, and wirings 11 configured to connect the sensors 20 and the circuit board 30.
  • Fig. 2 is a cross-sectional view schematically showing an example of a cross section of the textile type device shown in Fig. 1 taken along surface A-A.
  • the wirings 11 are provided in a wiring film 10.
  • the wiring film 10 is disposed between the cloth 50 and one of the sensors 20 and a protective layer 21.
  • a wiring layer 13 and an adhesive layer 15 constituting the wiring film 10, the sensor 20, the protective layer 21, and the cloth 50 are actually in contact with each other, but are shown by being partially separated for the sake of helping understanding thereof.
  • the wiring film 10 shown in Fig. 2 includes the wiring layer 13 and a short-circuit prevention layer 15.
  • the wiring layer 13 includes an extensible film 12 and a wirings 11 provided along the extensible film 12 inside or on an outer surface of the extensible film 12.
  • a part of the wirings 11 is exposed from at least a first surface 13a of the wiring layer 13 on the sensor 20 side.
  • the part of the wirings 11 is exposed from the first surface 13a so that the wiring 11 can be in contact with the sensor 20.
  • the wiring film of the present invention in order to bring the wirings into contact with the sensor while securing insulation of the wirings, only a part of the wirings may be exposed from the first surface.
  • the wirings are provided inside and on the outer surface of the extensible film.
  • stretchable wiring such as a conductive thread, a conductive wire, a conductive ink, or the like
  • a "conductive thread” refers to a natural fiber or a chemical fiber coated with a conductive material
  • a "conductive wire” refers to a wire-like member made of a conductive material.
  • the conductive wire is typically a metallic wire, but is not limited to a metallic wire as long as the conductive wire has conductivity. Particularly, it is desirable to use a conductive thread or a conductive wire for the wirings 11 and it is more desirable to use a conductive thread coated with silver and a copper wire as the conductive thread and the conductive wire, respectively.
  • the conductive thread is a thread having conductivity.
  • the conductive thread has high durability and high conformability to changes in shape. For this reason, deformation or the like of the textile type device 100 can also be prevented using a conductive thread.
  • a copper wire has high conductivity and low variation in resistance.
  • conductive threads are used for wirings between sensors like in conventional motion capture and copper wires may be used for wirings of a digital device (in which high conductivity is required) for the purpose of adding further functions.
  • the wirings 11 may be used by being coated with an insulating material. In this case, a portion exposed from the first surface of the wiring layer facing the electronic component is not coated with an insulating material.
  • a meandering shape can be any shape such as a zigzag, a waveform, a curve obtained by aligning a plurality of horseshoe shapes and/or parts of horseshoe shapes and joining or interpolating between ends thereof, a continuous hairpin curve, a line obtained by combining a plurality of parts of polygons, and a line obtained by combining a plurality of parts of star shapes, or combinations thereof, a substantially straight line and an approximate curve, and combinations of a substantially straight line and an approximate curve.
  • a period of meandering and a width of meanders can have any values. Furthermore, meanders may not have the same shapes, the same period, and/or width and may have different values. When the wirings 11 such as the conductive thread or the conductive wire meander, conformability to the deformation of the extensible film 12 can be improved.
  • any member having stretchability can be used for the extensible film 12. Since the extensible film 12 stretches and contracts, a textile type device 100 which can conform to deformation such as stretching and bending can be obtained.
  • an amount of change in shape with respect to an initial state is preferably 30% or more, more preferably 50% or more, and particularly preferably 100% or more.
  • a thickness of the extensible film 12 is not particularly limited, the thickness thereof is preferably 5 ⁇ m to 300 ⁇ m and more preferably 10 ⁇ m to 100 ⁇ m. Both high stretchability and strength can be achieved as long as the thickness of the extensible film 12 is in this range.
  • the extensible film 12 is constituted of an adhesive layer 12A and an insulating layer 12B from the first surface side of the extensible film.
  • the adhesive layer 12A is thermally melted, the wiring film 10, the sensor 20, and the protective layer 21 can be fused and joined.
  • the insulating layer 12B any member having stretchability such as a polyurethane film can be used.
  • the adhesive layer 12A is preferably a thermoplastic adhesive layer and examples of thermoplastic adhesive layer include known hot melt films and the like, but it is desirable that the adhesive layer 12A be a hot melt film having stretchability.
  • a hot melt having stretchability examples include a hot melt film or the like having polyurethane as a main ingredient.
  • a conductive hot melt containing conductive metal particles may be partially used between contact points of the sensor 20 and the wirings 11. Thus, an electrical connection between the sensor 20 and the wirings 11 can be improved so that contact resistance is reduced.
  • conductive metallic fine particles used for the conductive hot melt silver, gold, copper, platinum, or aluminum is preferable, silver, gold, or copper is more preferable, and silver is most preferable. Furthermore, using flake-like metallic fine particles, high conductivity can be imparted with a small content. It is desirable that the conductive hot melt include a hot melt having polyurethane as a main ingredient. Thus, detaching from the sensor 20 or the wirings 11 due to distortion applied at the time of the cloth stretching and contracting can be minimized.
  • the extensible film 12 is not limited to this embodiment.
  • the extensible film 12 may be constituted only of the insulating layer 12B made of a polyurethane film, adhesive layers may be formed on both surfaces of the insulating layer 12B, and the extensible film 12 may be constituted only of an adhesive layer. Modifications thereof will be described below in detail.
  • the short-circuit prevention layer 15 is disposed on a second surface 13b of the wiring layer 13 opposite to the first surface 13a. In the wiring layer 13, if the wirings 11 are not exposed from the second surface 13b, the short-circuit prevention layer 15 may be omitted. However, as the short-circuit prevention layer 15 is provided on the second surface 13b of the wiring layer 13, a short circuit due to penetration of sweat or the like from the cloth 50 can be more effectively prevented.
  • the present invention can also be used underwater or the like.
  • the short-circuit prevention layer 15 also has a function of adhering the wiring layer 13 to the cloth 50.
  • the textile type device 100 functions as a wearable device. For this reason, it is assumed that washing or the like is performed.

  • a hot melt having stretchability include a hot melt or the like having polyurethane as a main ingredient.
  • the short-circuit prevention layer 15 includes the insulating layer 15B
  • the short-circuit prevention layer 15 can embed the wirings 11 exposed from the second surface 13b of the wiring layer 13 on the cloth 50 side, thereby further improving insulating properties.
  • short circuiting of the textile type device due to sweat or the like can be minimized.
  • the strength of the entire wiring film 10 can be further increased. It is desirable to use a polyurethane film as the insulating layer 15B. Thus, high insulation properties can be ensured and conformability at the time of the cloth stretching and contracting is improved.

  • Thicknesses of the adhesive layers 15A and 15C are preferably 10 ⁇ m to 200 ⁇ m and more preferably 30 ⁇ m to 100 ⁇ m. When the thickness of the adhesive layer 15C is within this range, the cloth and the wiring film 10 can be strongly adhered to each other and can be used for a long period of time without becoming detached due to washing or the like.
  • the wiring film 10 constituted of the wiring layer 13 and the short-circuit prevention layer 15 preferably has a conductivity when a shape thereof has changed by 10% or more that is 1/10 to 10 times a conductivity when the shape thereof has not changed. Furthermore, it is desirable that a proportion of conductivity change be kept in this range even if the shape thereof changes by 30% or more, it is more desirable that the proportion of conductivity change be kept in this range even if the shape thereof changes by 50% or more, and it is particularly desirable that the proportion of conductivity change be kept in this range even if the shape thereof changes by 100% or more.

Depending on usage applications, the sensor 20 may be replaced with an electronic component other than a sensor.
  • the sensor 20 is not particularly limited as long as a current or a voltage of the sensor changes due to a change in a physical quantity, but is preferably a variable resistance type sensor whose resistance varies depending on a physical quantity and a voltage of which at both ends changes, due to the simplicity or the like of a circuit.
  • the physical quantity at least one of the group consisting of sound, light, temperature, pressure, and strain can be suitably used.
  • a resistance value of the resistance of the sensor 20 is preferably 50 times or more a wiring resistance of the wirings 11.
  • a distance between the sensor 20 and an external output means 5 differs depending on a location, but the resistance of the sensor 20 is set to a value that is 50 times or more the wiring resistance so that an influence of the wiring resistance of the wirings 11 can be eliminated.
  • a sensor using ink is a sensor prepared using ink obtained by mixing conductive particles with an elastomer solution or a dispersion. By printing and drying this ink, a sensor in which the conductive particles are randomly dispersed in an elastomer film is obtained. In the sensor, distances between conductive particles change in accordance with thermal expansion/contraction due to tension, compression, and change in temperature and thus the resistance between both ends of the sensor changes.
  • a sensor using ink is very thin and conformability to an object on which measurement is to be performed is high. For this reason, accurate and stable measurement can be performed.
  • the protective layer 21 covers the wiring film 10 and the sensor 20 in a plan view.

  • the textile type device can also be used underwater.
  • the protective layer 21 is the outermost surface when the textile type device is used as described above.

  • a thickness of the protective layer 21 is preferably 5 ⁇ m to 300 ⁇ m and more preferably 10 ⁇ m to 100 ⁇ m. High stretchability and strength can be maintained as long as the thickness of the protective layer 21 is in this range.
  • Fig. 3 is a cross-sectional view schematically showing an example of a cross section of the textile type device shown in Fig. 1 taken along surface B-B.

  • the protective layer 21 and the wiring film 10 are provided only in a necessary minimum portion along the wirings 11 in this way so that a space K to which nothing is attached is formed above the cloth 50. Due to the presence of the space K, air permeability and flexibility of the textile type device 100 can be further improved.
  • the portions along the sensor 20 and the wirings 11 are preferably in a range of 0.1 mm to 100 mm from outer peripheries of the sensor 20 and the wirings 11 in a plan view and more preferably 0.5 mm to 5 mm. If the portions along the sensor 20 and the wirings 11 are too large, there are more unnecessary portions and thus air permeability of the textile type device is hindered. On the other hand, if the portions along the sensor 20 and the wirings 11 are too narrow, a part of the sensor 20 and the wirings 11 is highly likely to be exposed to the outside due to a level difference between the sensor 20 and the wirings 11 and a short circuit is highly likely to occur.
  • cloths can be used as the cloth 50.

  • FIG. 14 is a schematic cross-sectional view of a device transfer sheet according to an embodiment of the present invention.
  • a device transfer sheet 200 according to the embodiment of the present invention includes a wiring film 10, a sensor 20, a protective layer 21, and a temporary support 60.
  • the device transfer sheet 200 When the device transfer sheet 200 is transferred to a cloth and the temporary support 60 is detached, the device transfer sheet 200 functions as a textile type device of the present invention like the textile type device 100 to 103 described above.
  • An example shown in Fig. 14 is a case in which the textile type device 100 is provided, the wiring film 10, the sensor 20, and the protective layer 21 have the same constituents as those of the textile type device 100, and detailed description thereof will be omitted.
  • the temporary support 60 is a support part configured to support the wiring film 10, the sensor 20, and the protective layer 21 until the textile type device is transferred to the cloth.
  • the temporary support 60 is detached when the textile type device is used.
  • a material of the temporary support 60 is not particularly limited.
  • a commercially available polyethylene terephthalate (PET) film or the like can be used.
  • a thickness of the temporary support 60 is preferably 20 ⁇ m or more, more preferably 50 ⁇ m or more, and particularly preferably 100 ⁇ m or more. If the thickness of the temporary support 60 is in this range, the wiring film 10, the sensor 20, and the protective layer 21 can be sufficiently supported. On the other hand, if the thickness of the temporary support 60 is too thick, there is a problem that the manufacturing costs of the entire device transfer sheet 200 increase and a thickness and weight thereof unnecessarily increase.
  • the electronic component to which the wirings are connected can be easily transferred to the cloth and a short circuit of the wirings can be prevented.
  • a method for producing a device transfer sheet includes a step of forming wirings on an extensible film to prepare a wiring film, a step of preparing a sensor-attached film having a sensor formed on a temporary support with a protective layer therebetween, and a step of adhering the wiring film to the sensor-attached film such that the wirings and the sensor are connected.
  • the sensor is used as an example of an electronic component.
  • a wiring film is prepared.
  • the conductive thread is sewn into an extensible film. Since the extensible film is thin, the extensible film is very easily torn, but a thin needle and a conductive thread having a small frictional force are used so that breakage of the extensible film can be prevented.
  • Embroidering machines, sewing machines, or the like may be used for sewing or manual sewing may be used. The same applies to a case in which a metallic wire is used.
  • the wirings are formed such that at least a part thereof is exposed from one surface of the wiring layer.
  • a conductive thread is used, the conductive thread is exposed on at least one surface of the wiring layer if the conductive thread is sewn to pass through both surfaces of the extensible film.
  • blindstitching is a sewing method in which a needle inserted from one side passes through an inside of a film and is pulled from a surface on the side on which the needle is inserted.
  • the short-circuit prevention layer is provided on a surface of the wiring layer opposite to a surface thereof adhered to the sensor if necessary.
  • the short-circuit prevention layer can be formed on one surface of the extensible film with a thermoplastic film or the like which is thermally melted therbetween.
  • the sensor-attached film is prepared separately from the preparation of the wiring film.
  • a method for preparing a sensor-attached film can be obtained by sequentially stacking the protective layer and the sensor above the temporary support.
  • a commercially available PET film can be used as the temporary support.
  • the protective layer is formed above one surface of the PET film.
  • the protective layer may be formed by printing a polyurethane resin or sticking a commercially available polyurethane film thereon.
  • a sensor using ink can be prepared using screen printing at a predetermined position on the obtained protective layer. With such a procedure, the sensor-attached film can be obtained.
  • the obtained wiring film and the sensor-attached film are adhered.
  • the adhesion is performed such that the wirings and the sensor are electrically connected.
  • an adhesive layer is formed on at least one of the adhesive surfaces of the wiring film and the sensor-attached film. For this reason, the surface from which the wirings of the wiring film are exposed and the surface on which the sensor of the sensor-attached film is formed is aligned, are subjected to heat application, and are adhered. With such a procedure, the device transfer sheet can be obtained.
  • the protective layer and the extensible film constituting the wiring film are formed on the entire surface of the device transfer sheet.
  • the sensor and the wirings constituting the wiring film are supported by the temporary support even if unnecessary portions are removed.
  • the device transfer sheet can be easily produced without complicated steps. For this reason, mass production can also be improved.
  • a method for manufacturing the textile type device includes a step of adhering the device transfer sheet to the cloth and a step of detaching the temporary support from the adhered device transfer sheet.
  • An outermost surface of the device transfer sheet opposite to a surface on which the temporary support is provided is an adhesive surface. For this reason, the device transfer sheet is positioned and heated at a predetermined position on the cloth and thus the cloth and the device transfer sheet are fused and joined. In the device transfer sheet, the sensor, the wirings, and the like are already provided in a predetermined arrangement. For this reason, the device can be transferred to a desired position simply through adhesion. Furthermore, since support is performed by the temporary support, the shape does not change significantly at the time of adhering and the accuracy of transfer can be improved.
  • the temporary support is detached from the device transfer sheet. With such a procedure, the textile type device can be easily obtained.
  • the textile type device can be produced in a necessary portion simply by transfer using the device transfer sheet. Furthermore, since the device transfer sheet has stretchability, flexibility, and stability, the accuracy of the positioning can be improved and the resolution of data can be further improved.
